ALTERNATEUR INTELLIGENT

INTELLIGENT CHARGE ALTERNATOR

Abrégé français

Alternateur intelligent pouvant fonctionner avec deux batteries ou plus, lesquelles sont chargées individuellement et raccordées individuellement ou en série à l'alternateur. Chaque encoche du stator loge au moins 2 bobinages en parallèle, chacun des enroulements étant autonome. Le dispositif nécessite un support de diodes pour chaque enroulement monté en parallèle, soit en étoile, en triangle, biphasé ou monophasé, et peut être raccordé en série. Les batteries peuvent également être raccordées individuellement ou en série, entre pôles négatif, positif, négatif, etc. Les tensions sont ainsi additionnées et chargent les batteries déchargées sans toutefois surcharger celles qui le sont déjà.

Abrégé anglais

An intelligent charge alternator is disclosed and is adapted to operate with
two or more batteries which are individually charged, alone or connected in
series. In each stator slot there are 2, 3, 4, etc., windings in parallel and each
coil is independent to the other. It requires a rectifier bridge for each coil in
parallel, either star, triangle, diphase, or single-phase winding and can be
connected in series. The batteries can also be connected individually or in series
between negative positive negative pole, etc., adding in this case the voltages, but
it will charge the discharged battery in amperes and it will not charge the charged
battery with over potential.

INTELLIGENT CHARGE ALTERNATOR
FIELD OF THE INVENTION
The present invention relates to electrical energy generators, and more
specifically to alternators capable of non-destructive batter,v charging.
Background of the Invention
In equipment such as tractors, buses, road machinery, aircraft and the like
there are AM-FM radios, telephones, BLU, BHF, fans, cassette-players all of
which require 12 volts to operate. Often, such equipment is connected to one or
more 12 volt batteries, which in turn are connected to an alternator.
In conventional 24/28 volt alternators, 24 volts is for two batteries of 12
volts discharged and 28 volts with all its limited charge. A voltage regulator
stops this voltage which is 14 volts or 28 volts depending on the alternator
design. A problem which exists in conventional alternators is that, in two battery
equipment of 12 volts+12 volts (under rest or discharged) and 14 volts+14 volts
in the case of its full charge, as in the example above, the equipment is
connected to the first battery, then nothing can be connected to the second 12-24
volt battery. This is because at least one of the equipment pieces would burn out
since it would have a 12 volts potential to ground. That is to say, the 0-12 volt
battery consumes current to feed all this equipment, thus lowering the potential to
less than 12 volts until it is completely discharged.
Therefore, in a conventional system a start would be difficult or nill since,
although the 12-24 volt battery is completely charged, the 0-12 volt battery is
not. The 0-12 volt battery lowers its potential until 0, so that it does not start. If
it would, the following process would take place: the 0-12 volt battery would
remain at 12 volts and the 12-24 volt battery, the last one at its full charge, one

CA 022400~9 1998-06-09
would increase up to 15 or 16 volts, totalling 28 volts; the regulator would close
and it would not charge the 0-12 volt battery.
To sum up, the 0-12 volt battery is destroyed due to the lack of slllf~tin~
charge and the 12-24 volt battery is destroyed by overvoltage, water depletion for
S excessive potential and also by overheating. In a 24 volt conventional system,
where sometimes a starter, alternator and 24 volt lights are used, such problemsoccur with the use of 12 volt equipment, and others have a device called parallel-
series. This one is frequently out of work, leaving the machine without starter
and battery, causing serious problems in the end.
Summary of the Invention
An object of the present invention is to provide means in the form of an
intelligent charge alternator, to fully charge at least one discharged battery while
not over charging any other battery that is fully charged, thus not ~1~m~gin~ the
charged batteries.
To accomplish this object, the intelligent charge alternator of the present
invention is provided with two or more coil windings; wherein the coil windings
are star, triangle or mono-phase windings, and wherein the coil windings are in
parallel, the coil windings in the same slot, and the coil windings in each slothave the same number of turns thus obtaining the same voltage.
According to a broad aspect, the invention relates to a charging alternator
for charging two or more batteries. The alternator comprises at least two
windings, the windings being either star, triangle or mono-phase in form and theat least two windings being parallel and located in the same slot. Each coil in
the same slot has the same number of turns to thereby obtain the same voltage.

Detailed Description of Preferred Embodiments of the Invention
Referring to Figures 1 and 2 the alternator of the invention has star,
triangle or monophase windings. The windings are realized in parallel, and as
many parallel windings are provided as batteries in use, and are independent
among the parallel coils. Each winding has its own plate rectifier with three
positive diodes 40 and three negative diodes 30, totalling six diodes. Therefore,
two windings will have two rectifier bridges; three windings will have three
rectifier bridges, four windings will have four rectifier bridges and so on. Thealternator of the invention may be used with at least the following battery
connections: 12 volts+12 volts, 24 volts+24 volts, 7 volts+7 volts or 24 volts+12
volts+6 volts. By way of example, it is preferred to design 12 volts+l2 volts+6
volts+24 volts. The first battery is connected to a parallel winding with six wire
turns, the second battery is connected to a winding with six turns, the third
battery is connected to a winding with three turns and the last battery, which is
24 volts, is connected to a winding with twelve turns. All windings have
individual rectifiers connected in series, -12+-12-6+-24+= 54 volts. In the charge
mode, the voltages would rise to the following values 14+14+7+28, all uniform.
The batteries are connected in series or parallel to the rectifier bridges.
Figure 1 shows a scheme of a series connection and Figure 2 shows a scheme of
parallel connection. The batteries may have a different current, the one with less
current will receive the corresponding charge until its complete charge, being
either a 12 volt battery and 35 amperes or up to more than 220 amperes. In this
case the complete charge is delayed a bit more; the values in voltage are strict 6-
7 volts for 6-7; of 12-14 volts for 12/14 batteries, according to the winding of

stator 20 with regard to the voltage. But current varies according to the needs at
the start or the amount of current used. In each positive/negative joint of the plate
rectifier there is a bridge connected to the respective bridge of the corresponding
battery, according to plane of the stator 20, two parallel windings and two
rectifier plates bridge connected in series but parallel bridge rectifier with
batteries.
If the first battery is discharged and the other batteries are charged, the
alternator of the invention will fully charge the discharged battery, and the
charged batteries will not receive any current because it is not necessary. In this
case we would use a 24 volt to 28 volt regulator to stop. The rotor 10 feeding
that would be 24/28, from the second bridge with three diodes or feed it with the
start key as with any other conventional alternator. An alternator can be
designed 12/14/12/14, which is used frequently, but with binding posts the
bridges can be connected in parallel, i.e. 12/14, and thus double the current. If in
24/28 the current would be around 100 amperes or more, after that it would be
200 or more, but the intelligent charge alternator according to the invention aims
to solve the aforementioned problem with regards to the equipment using 0-12
volts. It may be the case when all the batteries are discharged, this alternator will
charge all of them until fully complete, that is 14-7, 28 volts or 14+14 as in the
last case.
The rotor 10, Figure 3, is conventional, but we must take into account the
voltage to use. The most common one is 12/14 volts or 24/28 volts, the last one
being the best one to solve the problem mentioned above. The regulators are the
most conventional ones, such as, 12/14 volts or 24/28 volts. The stator 20 is also
conventional, or having certain adjustments if necessary. The cover on the
collector side is lengthened to house 2-3-4, etc. rectifiers or it can be designed to
house half of them on the pulley side cover and the other half on the collector
s1de cover.
Figure 3 shows an exploded view of the intelligent charge alternator of the
invention. The order of assembly is as follows: female screw 100, grover washer

102, double pulley 104, turbine 106, rear cover 108, spacer 110, bearing 112,
spacer 114, axle box 116, rotor 10, spacer 120, bearing 122, bearing 124,
collector 126, front cover 128, small cover 130, brushes 132, and cover 134.
The windings can be aluminium, copper, silver, superconductives, or other
like material.
Regulators should have enough capacity for the design and current
consumption of the rotor 10.
An alternator can be designed for two or more batteries with the poles as
shown in Figure 4.
The rotor 10 can also be fed by +B without the three auxiliary diodes 50.
The rotor 10 can be conventional and the most convenient one, the same with the
voltage 6/7, 12/14, 24/28 volts. The stator 20 is the same as the conventional
type, but it can be designed for numbers of revolutions, current, its winding,
slots, according to the requirements, the collector side cover is lengthened to
house the diode bridges being 2-3-4 etc., and the pulley side cover can also be
lengthened and house there half of the rectifier bridges.
The intelligent charge alternator according to the invention can be used for
the construction of either high or low energy production alternators.
While the invention has been described in connection with a specific
embodiment thereof and in a specific use, various modifications thereof will
occur to those skilled in the art without departing from the spirit and scope of the
invention as set forth in the appended claims.
The terms and expressions which have been employed in this specification
are used as terms of description and not of limitations, and there is no intention
in the use of such terms and expressions to exclude any equivalents of the
